... The eighth bit of the device address is the read/write operation select bit. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low. Upon a compare of the device address, the EEPROM will output a zero compare is not made, the chip will return to a standby state. Technology ACE24C02A Two-wire Serial EEPROM VER 1.2 7 ...
